Mercury in Libra opposite Chiron Rx in Aries (4 deg)
Mercury in Libra wants to say the nice thing and gloss over the painful stuff. The opposition to Chiron says this will be difficult, because almost anything will activate a sore spot or sound awkward. In fact, you may find that more you try to be polite, the more likely you are to say the wrong thing. Wounds/sensitivities may be projected so that everything sounds hurtful. Watch for backhanded compliments (passive-aggressive) or compliments that are genuine but rub someone the wrong way (unintentionally hurtful).
Compromise and diplomacy will not be favoured. You probably won’t see the painful words coming because Mercury in Libra is not blunt. Focus on the unpleasant issue and talk about it as best you can. Accept that the discussion will not be smooth, but Chiron shouldn’t be ignored. This could also be a good time to apologize.
